Application filed. March 3, 1915.

To all whom it may concern Be it known that 1, WILLIAM C. HEDG- coon, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Truck- Pedestals, of which the following is a specification.

My invention relates to truck pedestals and has particular reference to a novel construction for tying together the lower ends of the pedestal jaws. A similar construction is shown in my copending application, Serial No. 11,665.

In many types of car trucks, particularly those used under passenger cars, the journal boxes are reciprocable between pedestal jaws, the lower ends of the jaws being usually tied together by a strap extending between adjacent pedestals, this strap being secured to the lower ends of the jaws by a simple bolt. The blows applied to the pedestal in starting and stopping are severe, and run less the lower ends of the jaws are tied securely to each other, such blows will be taken up by one jaw alone, with the result that breakage frequently occurs at the angle between the vertical and horizontal memhers.

An object in the present construction is to provide means for securely tying together the lower ends, such means comprising, in the present instance, a bar which interlocks with the lower ends of the jaws and operates in conjunction with the usual strap to transmit blows applied to one jaw to the mating jaw.

The invention will be more readily understood by reference to the accompanying drawings, in which Figure 1 is a side elevation partly in section of a car truck pedestal constructed in accordance with my invention, Fig. 2 is a bottom plan view thereof, and Fig. 3 is an end or edge elevation of the construction shown in Fig. 1.

Referring more particularly to the drawings, it will be seen that the pedestal may Specification of Letters Patent.

Serial No. 11,664.

consist in a horizontal plate 10 and two vertical depending legs 11, 12. The lower ends of the legs 11, 12 are normally unconnected, providing an open space through which the journal box may be inserted. In order to securely tie together the jaws and transmit blows from one to the other thereof, I pro vide a bar which extends between the free ends o1 the jaws, this bar consisting in a pair of members 13 joined at their ends by a body or metal 14 which terminates in lugs 15. These fit closely against stops or abutments 16 on the lower end of the jaws. The metal forming the end 14 is hollowed out or recessed to accommodate a tie bar 17, which, as shown, may extend merely across the lower end of the pedestal and may be joined by a second strap 18. These straps are apertured to register with similar aperture in the part 14, and all the parts are held in proper position by bolts 19. By the use of the construction shown, parts are securely interlocked together as far as any force is concerned which tends to separate the jaws from each other. Thus the forces in starting or stopping are shared equally by the two pedestal jaws.

I claim:

1. A car truck pedestal having jaws, a bar interlocking with said jaws and serving to tie the same together, said bar having a re cess, and a tie strap accommodated within said recess, substantially as described.

2. In a car truck pedestal, the combination of depending jaws, a skeleton bar having hooked ends, the end portions of the bar engaging said jaws and preventing spreading thereof, a tie strap accommodated in said bar, and means for securing said tie strap and bar to said jaws, substantially as described.
